Can Lucene index the openstreetmap.org (OSM) node db (400M latitude/longitude pairs), and then find the 20 nodes closest to a given latitude/longitude?
More specifically: % Can Lucene index numerical data and understand that 16 is close to 15, but far away from 160000? % Is Lucene reasonably fast indexing 400M floating point pairs? % After Lucene creates the 400M index, can it return search results reasonably fast? % Is there a guide/tutorial that shows how to use Lucene to index numerical data (I'm using Plucene, but I'll settle for any sort of guide)? I tried to index OSM data w/ SQLite3, but it took forever. I realize I could use MySQL/PostgreSQL, but I'm looking for an embedded/serverless solution. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
